Product Description
The ReadyBoard 800 is a mid-sized, EPIC-compatible, affordable, high quality single-board system,
which contains all the component subsystems of a PC/AT PCI motherboard plus the equivalent of up to
5 PCI expansion boards. The ReadyBoard 800 is based on one of the ultra high performance, high-
integration Intel Pentium M or Celeron M processors. These processors with the matching chip set give
designers a complete integration solution with a high performance embedded processor based on the
EPIC form factor that conforms to the Revision 1.1 of the EPIC standard.
Each ReadyBoard 800 incorporates a Intel® 8556ME chipset for the Memory Hub (Northbridge) and
I/O Hub (Southbridge) controllers. This includes the Intel 82855GME memory hub, which controls
graphics and memory interface and the Intel 82801DBM I/O Hub Controller for I/O functions. The
Winbond Electronics Corp., Super I/O controller W83627HF, adds I/O functions. Together, the Intel
and Winbond chips provide four serial ports, a floppy or EPP/ECP parallel port, four USB 2.0 ports,
PS/2 keyboard and mouse interfaces, an Ultra/DMA 33/66 IDE controller supporting two IDE drives
and one CompactFlash socket, AGP 4x graphics equivalent controller, which provides CRT and LVDS
flat panel video interfaces for the most popular flat panels, and an audio AC'97 CODEC on the board.
The ReadyBoard 800 also supports two independent Ethernet interfaces, 10/100BaseT and 1000BaseT,
and up to 1GB of ECC or non-ECC DDR RAM in a single 200-pin SODIMM socket.
The ReadyBoard 800 can be expanded through the PCI-104 expansion bus to accept the PCI-104 cards
that offer compact, self-stacking, modular expandability for additional system functions. If required for
an application, the PC/104 bus, an embedded system version of the signal set provided on a desktop
PC's ISA bus is provided by the optional Ampro MiniModule ISA expansion board. The PC/104-Plus
bus includes this signal set, and in addition, includes signals implementing a PCI bus, available on an
additional 120-pin (4 rows of 30 pins) PCI expansion bus connector. The ISA bus operates at 8MHz
clock speed and the PCI bus operates at 33MHz clock speed. See Figure 2-2.
Among the many embedded enhancements on the ReadyBoard 800 that ensure embedded system
operation and application versatility are a watchdog timer, serial console support, battery-free boot,
customizable splash screen, on-board high-density CompactFlash card, and Ampro BIOS extensions for
OEM boot customization.
The ReadyBoard 800 is particularly well suited to embedded applications and meets the size, power
consumption, temperature range, quality, and reliability demands of embedded system applications. It
can be stacked with Ampro MiniModules™ or other PCI-104 compliant expansion boards, or it can be
used as powerful computing engine. The ReadyBoard 800 only requires a single +5V power supply.
